JEWE'LlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 293,249, "dated February 12, 1884:.

Application filed May 21, 1883. (Model) To aZZ whum it may concern.-

Be it known that I, ERVIN HOMRIGHOUS, a citizen of the United States, residing at Shelbyville, in the county of Shelby and State of Illinois, have invented a new and useful Ma I jeweling-tools used with this machine.

ends to the head of the centering-tool a.

Similar letters indicate like parts in all the figures. I

My invention relates to improvements in machines for jeweling watches; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims.

In the accompanying drawings, J represents a circular faceplate, provided with a central opening, 0*, and opposite lugs, e 6, having central holes for the passage ofthe screws of the clamps O O, by means ofwhich the watch plate or bridge B is secured to the face-plate J by means of the thumb-nuts h.

P represents aframe, secured at its lower end to the circumference of the face-plate J, and provided with the parallel lugs H I, having central holes, the former of which is threaded to receive the hollow screw-nut g.

B represents a hollow spindle, which passes through the central hole in the lug I and through the hollow screw-nut Q, and is screwthreaded at its lower end, as shown in Fig. 2, to be screwed to a centering or other tool, hereinafter described.

t represents a handle secured to the hollow spindle B near its upper end.

1 represents a hollowscrewnut secured to the handle 73.

0. represents a centering-tool, provided wit tapering spring-jaws, secured at their upper The head of the centering-tool a is provided with a central threaded hole, and is screwed upon the lower end of the hollow spindle B.

K represents a spreader or red threaded at.

its upper end, and passing through the hollow screw-nut 1, thence through the hollow spin-- dle B, the centering-tool a, thence passes through the hole in the work and the hole a" in the face-plate J. The spreader K, by its operation, serves to spreadllaterally the jaws of the centering-tool a, to fill up the hole in the watch plate or bridge It. provided near its middle with a flattened surface, s. (See Fig. 2.) E is a pin passing through the hollow spindleB and over the flattened surface on the spreader K, and thereby prevents the latter from turning, excepting with the hollow spindle B.

0 represents a friction spring, to press against the hollow spindle B and hold it in position.

b (see Fig. 3) represents a bezel-opener, the head of which is provided with a threaded central hole, adapting it to be screwed on the end of the hollow spindle B after the centering has been completed and it is desired to open the bezel for the reception of the jewel.

Fig. 4: represents a closer and burnisher, intended to turn down the bezel on the jewel after it is in place; and Fig. 5 represents a bed The spreader K is and bezel-cutter designed expressly for new work. V

' All these attachments are to be made of steel, are adjustable to any size required, and are interchangeable on the end of the hollow spindle B.

The pressure of the spring 0 on the hollow spindle B is sufficiently great to hold it in any desired position to which it may adjusted, and the function of the hollow screw-nut Q'ds to adjust the tool secured to the lower end of the hollow spindle B downwardly by screwing the nut Q down until its lower end comes in contact with the head of the tool and forces the latter and the hollow spindle down against the tension of the spring 0. Thetool is adjusted upwardly by screwing up the hollow screwnut Q, and then raising up the hollow spindle B and its attached tool bodily by the handle 15, the spring 0 holding the hollow spindle and its attached tool in its raised position.

The operation of the machine is as follows:

The watch plate or bridge is placed upon the faceplate of the machine, the centering rod or spreader introduced into the old jewel-open ing, and the centering-tool adjusted to thesize pletes the operation.

WVhat I claim as my invention is 1. In a machine for jeweling' watches, the

combination, with a hollow spindle journaled in a suitable frame over a face-plate provided with a central hole, of an expansible tool secured to the lowerend of the hollow spindle, a spreader passing through said spindle, and means for forcing the spreader downward to spread the jaws of the tool, substantially as shown and described.

2. In" a machine for jeweling watches, the

combination, with the face-plate J, provided with a central hole, 1', and frame P, secured to said faceplate, of the hollow spindle B, provided with handle 6, hollow nut 1, threaded spreaderK, and an expansible tool, snbstan tially as shown and described.

3. In a machine for jeweling watches, the combination, with the faceplate J, provided with a central hole, 0', and frame P, secured to said face-plate,.of the hollow spindle B, provided with handle 1', hollow nut Q, and threaded bracket H, substantially as described, and for the purpose set forth.

p 4:. In a machine for jeweling watches, the combination, with the frame P, provided with the bracket H and bracket I, of the hollow spindle B, the hollow screw-nut Q, and the spring 0, substantially as shown and described.

5. In a machine for jeweling watches, the

combination, with the face-plate J, having a central hole, 1", andframe P, secured to the face-plate, of the clamps O, hollow spindleB, handle 1', hollow nut 1, threaded spreader K,-

.l1ollow nut Q, and threaded bracket H, sub! staniially as shown and described.
